Starting a new thread because I believe this goes a bit beyond what I could get out of the film thread.

I currently use a Canoscan 9000f II and seem to get varied results out of it. Sometimes I get really sharp scans and other times I get images that are very unsharp, almost out of focus. I scan in tiff format and don't apply any presets or settings that the scanner offers, with some sharpness added inside of LR I get some decent results most of the time.

Now my question really is that am I developing wrong or am I scanning wrong, I don't know where the fault is but I know I'm doing something wrong to consistently get shitty results. Maybe I don't let my film dry long enough so it doesn't sit flat on the scanner? I only dry it for around 40 minutes.

Any tips would be great, also feel free to discuss other scanning related stuff in this thread.
